摘要
本文主要讨论了所设计的两个鱼用预混合饲料的特点及使用该预混合料对鱼类生产发育、饲料利用率及消化代谢的影响。结果表明,预混合料Ⅰ号与Ⅱ号可使鱼总产量分别提高14％及7.6％,鲤鱼产量提高20.9％及8.7％,饲料系数降低0.4及0.2个单位。通过消化试验发现,使用预混合料Ⅰ号及Ⅱ号可以提高鲤鱼的总消化率。并具有明显的经济效益。
The paper discusses the character of two premix formulas and their effects on fish growth,feed conversion rates and digestive metabolism. The results show that the addition of Premix 1 and 2 could increase the total fish produciton by 14% and 7. 6% respectively,and carp production by 20% and 8.7% respectively. Feed conversion rates were decreased by 0. 4 and 0. 2 unit respectively for Premix 1 and 2 of supplemented groups. Premix supplementation could improve carp digestive rates and give marked economical benefits.
